The Scale of The Universe

 

As the name suggests, this is a chart that compares the scale of objects in the universe, from simple cells to humans, moons and galaxies.

.

 

 The zoom allows you to examine just how big things are in comparison to another, and the reality is quite surprising

 

 

It also gives you a short bit of information on each object, such as which known star is the brightest
(Sirius A), the average temperature on Venus (450°C) and the largest known planet (TrES-4).
